S14 SR20DET, What wires are these???

[Sipo240]

Finally figured out most the wiring but still have questions about a few wires. Wasted alot of time tryin to follow a guide someone here did (the hand written one that was scanned) to find out that almost all of it was wrong !!!.

Where do you wire the
1- Power to Injectors (R/L) from the s14 plug,
2- ECU relay (R/B) from the S13 Gray Connector, and
3- ECU Relay (R/B) from the S13 Brown Plug ???

1. Ground any other black wires not noted here along with 10 and 23. There should be only one, but I forgot which one it is.
2. You will need to hook up the boost pressure sensor by cutting the pins off of numbers 24, and 39, extending the wire (cut some of the same shielded type from the KA harness), and soldering on the plug that connects directly to the sensor.
3. The location marked with the * is for the rear window defroster. Remove pin 11 and its wiring from the KA harness and splice it into the SR harness to ECU pin number 54.
4. Use the SR windshield wiper amp, cut the wiper motor plug off the SR harness and solder on the one from the KA harness. Match the wires up color for color when soldering the KA plug on to the SR harness.
5. You will need to take some pins from the KA harness connector in order to move pins from the small holes to the large ones and vice versa. There are only a few wires that need this done.
6. If swapping into a factory MT car, then reuse the tranny/power harness from the KA and solder the plugs from the SR tranny sensors on to it. If swapping into a factory automatic car, you will need to connect the VSS and reverse light switch to the vehicle wiring harness.







What I did was before taking pins out of the SR F4 plug, I labeled them all with numbers taken from the middle diagram. Then I pulled them all out and put them back in according to the top diagram. In the diagrams above, when you see bars connecting pins, it means you need to solder those wires together. So, for example, insert pin 29 into the plug, cut the pin off 31 and solder it to the wire attached to pin 29.

Good luck!!!
have fun
